Product details
Overview
SPD50N03S2L06GBTMA1 from Infineon Technologies is an N-channel enhancement-mode logic-level power MOSFET in TO-252 (D-Pak) package, rated for 30 V VDS, 6.4 mΩ RDS(on) at VGS = 10 V and ID = 50 A, with 175 °C maximum junction temperature and avalanche-rated operation. It delivers high current handling and low gate charge × RDS(on) figure-of-merit for efficient switching in DC-DC converters and motor control.
For engineers reviewing the SPD50N03S2L06GBTMA1 datasheet, SPD50N03S2L06GBTMA1 pinout, SPD50N03S2L06GBTMA1 application, or SPD50N03S2L06GBTMA1 equivalent, key selection criteria include RDS(on) at 4.5 V and 10 V, thermal resistance (RthJC = 0.7–1.1 K/W), avalanche energy (EAS = 250 mJ), diode forward voltage (VSD = 0.9–1.3 V), and dv/dt rating (6 kV/µs).
Technical Context
This OptiMOS™ power transistor uses trench-based silicon technology optimized for low conduction and switching losses. Its logic-level gate drive (VGS(th) = 1.2–2.0 V) enables direct interfacing with 3.3 V and 5 V microcontrollers without level-shifting circuitry.
The device integrates a robust body diode with trr = 41–51 ns and Qrr = 46–58 nC, supporting synchronous rectification and freewheeling in hard-switched topologies. Thermal design is supported by validated RthJC and transient ZthJC curves for PCB-level thermal modeling.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 30 V - Maximum drain-source blocking voltage; defines safe operating range in 24 V automotive and industrial bus applications. |
| RDS(on) @ VGS = 10 V | 4.7–6.4 mΩ - Low on-resistance enables <1 W conduction loss at 50 A, critical for high-efficiency power stages. |
| RDS(on) @ VGS = 4.5 V | 6.8–9.2 mΩ - Confirmed logic-level operation; supports direct drive from standard GPIOs without gate drivers. |
| ID (continuous) | 50 A @ TC = 25 °C - High current capability suitable for primary-side switches in 100–300 W SMPS and BLDC motor phase legs. |
| EAS | 250 mJ - Avalanche-rated for unclamped inductive switching; eliminates need for external snubbers in relay driving or solenoid control. |
| dv/dt rating | 6 kV/µs - Robust against parasitic turn-on in high-noise environments such as motor drives and industrial inverters. |
| Tj max | 175 °C - Extended thermal margin allows reliable operation in sealed enclosures or under sustained load conditions. |
Pinout & Package
Package: PG-TO252-3 (D-Pak), surface-mount, single-drain tab configuration with exposed drain pad for thermal conduction to PCB copper area.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Source) | Source terminal | Low-side reference node; connects to ground or current-sense resistor; carries full load current return path. |
| Pin 2 (Gate) | Control input | High-impedance MOSFET gate; requires <8 nC total gate charge for full turn-on; sensitive to ESD (±20 V absolute max). |
| Pin 3 (Drain) | Power output | Connected to high-side rail or inductive load; electrically and thermally tied to large copper pour via exposed tab. |
Key Features
| Feature | Design Value |
|---|---|
| Logic-level gate threshold | VGS(th) = 1.2–2.0 V ensures compatibility with 3.3 V MCU outputs and reduces gate driver complexity. |
| Low gate charge × RDS(on) | Qg = 52–68 nC and RDS(on) = 4.7 mΩ yield FOM < 320 mΩ·nC - minimizes combined switching + conduction loss. |
| Superior thermal resistance | RthJC = 0.7–1.1 K/W enables >100 W power dissipation with minimal heatsink when mounted on ≥6 cm² copper. |
| Body diode performance | VSD = 0.9–1.3 V and trr = 41–51 ns support efficient freewheeling with low reverse recovery loss. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar N-channel logic-level power MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IPB052N03LGATMA1 | Same VDS (30 V), lower RDS(on) (5.2 mΩ @ 10 V), higher Qg (78 nC), same TO-252 package. | Better conduction loss but slower switching; suited for lower-frequency (<100 kHz) high-current applications. | Prefer when thermal budget is tighter than switching speed requirement. |
| STL130N3LLH6 | 30 V, RDS(on) = 5.5 mΩ @ 10 V, Qg = 55 nC, same TO-252-3, but only rated to 150 °C Tj. | Limited high-temperature operation; not qualified for 175 °C automotive or industrial environments. | Select only where ambient temperature remains below 125 °C and extended thermal margin is unnecessary. |
Compared with IPB052N03LGATMA1 and STL130N3LLH6, SPD50N03S2L06GBTMA1 offers balanced switching-conduction trade-off and full 175 °C qualification-making it optimal for thermally constrained, high-reliability applications where both efficiency and ruggedness are required.

FAQ
Is SPD50N03S2L06GBTMA1 suitable for 3.3 V microcontroller gate drive?
Yes. With VGS(th) = 1.2–2.0 V and guaranteed RDS(on) of 9.2 mΩ at VGS = 4.5 V, it fully turns on using standard 3.3 V GPIOs. Gate charge is low (Qg = 52–68 nC), enabling fast switching without external drivers in moderate-frequency designs.
What is the maximum continuous drain current at 100 °C case temperature?
Per the ID vs. TC curve on page 3 of the datasheet, continuous drain current drops to approximately 32 A at TC = 100 °C. This derating reflects thermal limits-not electrical failure-and assumes proper PCB copper area (≥6 cm²) and no forced airflow.
Does this MOSFET have avalanche energy rating, and is it production-tested?
Yes, EAS = 250 mJ (single-pulse, ID = 50 A, VDD = 25 V). Per datasheet footnote 2, avalanche capability is defined by design and not subject to 100% production test-but it is qualified per AEC-Q101 and used in automotive-grade applications.
Can SPD50N03S2L06GBTMA1 replace a standard 30 V Schottky diode in OR-ing applications?
Yes, its integrated body diode has VSD = 0.9–1.3 V and trr = 41–51 ns, enabling active OR-ing with lower forward loss and controllable turn-off. Unlike passive diodes, it supports reverse current blocking and dynamic load sharing when paired with appropriate gate control.
